@Adri34219162fz9t,
Bottom line, I don't see a way other than converting. This is not my area of expertise; anyone who can set us both straight(er) is welcome!
From MediaInfo, this file is using for audio:
Format : AAC LC SBR Format/Info : Advanced Audio Codec Low Complexity with Spectral Band Replication Commercial name : HE-AAC
See this post from 2020:

There the user converted, believing the problem was variable frame rate. PR handles variable framerate better now. And I suspect the fix, back then, was not only because they converted to fixed rate in Handbrake, but that it converted the audio to more regular AAC. There is no mention of HE-AAC in PR supported formats. But I also did not find AAC LC, which is what Handbrake converted it to (below).
When imported to PR, the audio is running "slow." When I change the clip duration/rate to 200%, I can understand the dialogue, but it does not run full length. The clip itself has a lot of background noise, like traffic. In VLC player, the background noise is there, but the dialogue is clear and complete.
I converted in Handbrake, but I did not try to determine the right settings. I ended up with a (still variable frame rate) stereo clip that MediaInfo said was AAC LC. It worked correctly in PR.
Note that, for whatever reason, PR auto-tags this (original and handbrake versions) as SFX and applies "Heavy Reverb"). Or is that removing heavy reverb? lol. Just pick "clear audio type."
